Description

The present invention relates to boxes (toolboxes) for storing hand-held tools, such as an electric driver.
A toolbox includes a toolbox main body for storing hand-held tools, battery packs to be attached to the electric tools, and battery chargers, and a lid for opening and closing the toolbox main body. In general, a carrying handle is formed with the toolbox.
Japanese Laid-Open Patent Publication No. 2003-236772 (Japanese Patent No. 391692 ) teaches a technique for storing a rechargeable tool and a removable battery pack without causing bumping. Japanese Laid-Open Utility Model Publication No. 62-19183 discloses a toolbox for storing an electric circular saw and also teaches a technique for compactly storing a circular saw main body and a removable blade. Japanese Laid-Open Utility Model Publication No. 5-39879 teaches a technique for storing tools in various shapes and sizes.
However, these conventional toolboxes have been intended for storing tools after completion of work and for not using repeatedly or frequently bringing the tools in and out during the working process. The conventional toolboxes have been constructed to store the tools in a horizontal laying manner and thus, when the tools are temporarily stored within the toolboxes during the working process, users have to re-grip the tools to change from a horizontal laying position to a working position. Due to this, the conventional toolboxes have been inconvenient to use.
Thus, there is a need in the art for a multifunctional toolbox which can store the tools after completion of work and can serve as a tool keeping keeper or enabling to frequently bring in or out, and to temporally store the tools during the working process.
One aspect according to the present invention includes a toolbox for storing at least one hand-held tool having a tool main body and a handle portion extending from a side portion of the tool main body. The toolbox is constructed to be able to store the hand-held tool in a forward leaning position in which a front end portion of the tool main body and a rear end portion of the handle portion are supported by the toolbox.
Additional objects, feature, and advantages, of the present invention will be readily understood after reading the following detailed description together with the claims and the accompanying drawings, in which:

FIG. 1 is an overall lateral view showing a toolbox in an embodiment. The figure shows the electric tool stored and out.

Only the claims define the scope of the claimed invention. Therefore, combinations of features and steps disclosed in the following detailed description may not be necessary to practice the invention in the broadest sense, and are instead taught merely to particularly describe representative examples of the invention. Moreover, various features of the representative examples and the dependent claims may be combined in ways that are not specifically enumerated in order to provide additional useful embodiments of the present teachings.
An Embodiment of the present invention will be explained with reference to FIG. 1 - FIG. 7. FIG. 1 - FIG. 3 show an overall view of a toolbox 1 according to the embodiment. The toolbox 1 has a toolbox main body 2 and a lid 3 for opening and closing the toolbox main body 2. Both the toolbox main body 2 and the lid 3 can be made of aluminum. As shown in FIG. 1, a user may be positioned on the right side of the toolbox 1. In the following description, a side where the user is positioned is described as a front side, and the opposite side is described as a back side or a rear side.
The toolbox main body 2 has a substantially square box shape having a sufficient depth and an opening on the top. The toolbox main body 2 has a front wall portion 2a on the user's side, a left side wall portion 2b on the user's left side, a right side wall portion 2c on the user's right side, a rear wall portion 2d on the back side the front wall portion 2a, and a bottom portion (this portion is hidden by a seat portion 30 in FIG. 2). The lid 3 is supported via a pair of right and left hinge portions 4 on the upper part of the rear wall portion 2d so that the lid 3 can be open or closed in up and down directions. The lid 3 is locked in the closed state with a pair of right and left locks 5 mounted on the front side of the lid 3. A handle 6 is formed on the upper part of the front wall portion 2a of the toolbox main body 2. The user grips the handle 6 to carry toolbox 1.
As shown in FIG. 2, the seat portion 30 can be made of foamed urethane having an adequate cushioning property and placed inside the toolbox main body 2. FIG. 4 - FIG. 6 show the seat portion 30. Two electric tools 10 and a battery charger 20 can be positioned on the seat portion 30. The toolbox 1 of this embodiment is characterized mainly in the seated position of the two electric tools 10.
In this embodiment, the two storable electric tools 10 can be hand-held electric drivers each having a tool main body 11 in a substantially cylindrical column shape and a handle portion 12 extending laterally from the tool main body 11. A tool bit 13, such as a driver bit, is attached to a front end of the tool main body 11. A battery pack 14 is attached to a rear end portion of the handle portion 12. A trigger type switch lever 15, which can be pushed by a users fingertips, is formed on the base portion of the handle portion 12. When the switch lever 15 is triggered, an electric motor disposed within the tool main body 11 starts by receiving the supply of power from the battery pack 14, and the tool bit starts rotating.
The user holds the electric tool 10 by griping the handle portion 12 with the side of the front end portion (the side of the tool bit 13) of the tool main body 11 oriented forwardly, and in this state, the user pushes the switch lever 15 for performing a boring operation, etc.
As shown in FIG. 1, the user is positioned on the right side of the toolbox 1 (the front side of the toolbox 1) and brings in or out the electric tool 10 from a position obliquely upward as shown with an outlined arrow in FIG. 1. This allows the user to bring the electric tool 10 from the front side of the toolbox 1 into the toolbox main body 2 while keeping the same position as the working position and without changing the gripping position of the electric tool 10 to another position. Thus, the electric tool 10 can be stored in a standing and forward leaning position.
As shown in FIG. 2, the two electric tools 10 can be stored in parallel on right and left sides of the battery charger 20. The battery charger 20 can have a rectangle box shape. The battery charger 20 is stored at a position between the two electric tools 10 which are stored in the parallel manner on right and left sides of the toolbox main body 2. The electric tools 10 are stored in a forward leaning position such that the directions along their lengths (longitudinal directions) of the both electric tools 10 are oriented along the open or close direction of the lid 3.
Specifically, each of the front end portion of the tool main body 11 and the rear end portion of the handle portion 12 (i.e., the battery pack 14) of each of the electric tools 10 is supported by the seat portion 30, so that each of the electric tools 10 is stored in a position that the rear portion of the tool main body 11 extends obliquely upward from the seat portion 30 (the forward leaning position). Accordingly, the front end portion of the tool main body 11 is supported on the rear side portion of the toolbox main body 2, the rear end portion of the handle portion 12 is supported on the front side portion, so that each of the electric tools 10 is stored in the forward leaning standing position which is substantially same with the position that is taken when the user grips the electric tool 10 during the working process (a working position). FIG. 7 shows one of the electric tools 10 being supported on the seat portion 30 in the forward leaning position.
A pair of front end supporting portions 31 disposed on the right and left sides for supporting the main bodies 11 of the electric tools 10 and a pair of rear end supporting portions 32 disposed on the right and left sides for supporting the rear ends of the handle portions 12 are respectively (i.e. integrally) formed on the upper surface of the seat portion 30. On the right and left sides of the upper surface of the seat portion 30, the electric tools 10 are respectively supported in a standing position to extend between the front end supporting portions 31 and the rear end supporting portions 32.
As shown in FIGS. 4-7, each of the front end supporting portions 31 is formed in a raising manner from the upper surface of the seat portion 30, and has a supporting surface 31 a inclining upwardly towards the rear side and a fitting concave portion 31 b for fitting with the front end portion of the tool main body 11. The inclined supporting surfaces 31a is configured to contact the front end portion of the tool main body 11, and the fitting concave portion 31b is configured to accommodate a spindle of the electric tool 10.
The rear end supporting portions 32 are positioned at the front end portion of the seat portion 30 on the front side of the front end supporting portions 31. Each of the rear end supporting portions 32 has a V-shaped supporting recess 32a inclining deeper towards the front side and a fitting concave portion 32b for fitting mainly with the battery pack 14. As shown in FIG. 7, the handle portion 12 is fitted into the handle supporting recess 32a and the battery pack 14 is placed inside the fitting concave portion 32b.
In this way, each of the front end portions (spindles) of the tool main bodies 11 is fitted into corresponding one of the fitting concaves 31b of the front end supporting portions 31 of the toolbox main body 11, and each of the rear end portions of the handle portions 12 (the battery packs 14) is fitted into corresponding one of the handle supporting recesses 32a. Accordingly, each of the electric tools 11 is supported in the forward leaning position without falling off asides.
Cutting tool relieving concaves 33 are formed at the rear end part of the seat portion 30 (left end portion in FIG. 7) on the front end supporting portions 31 for mainly receiving the front ends of the tool bits 13 of the stored electric tools 10.
As shown in FIG. 2, supporting holes 34 are formed in the center of the upper surface of the seat portion 30. The supporting holes 34 can receive four legs (not shown of the battery charger 20) for preventing the movement of the battery charger 20 in the lateral direction (a direction parallel to the upper surface of the seat portion 30). In this embodiment, each of the supporting holes is formed to be shallow and to have a comparatively larger diameter in order to be compatible with battery chargers in various sizes.
According to the toolbox 1 of this embodiment described above, the electric tools 10 each having the handle portion 12 extending laterally from the tool main body 11 (which has a substantially cylindrical configuration) can be stored in a forward leaning position that is slightly leaned forwardly compared to a usual working position. In the forward leaning position, each of the rear portion of the tool main bodies 11 (the end portions toward the side of the user) is kept at a higher position than the tool bit 13. In addition, each of the base portions of the handles 12 is kept at a higher position than the battery pack 14. In this way, each of the handle portions 12 is positioned on the side of the user and in the forward leaning position. Due to this, each of the handle portions12 is easily gripped. Accordingly, the user can smoothly and easily bring the electric tools 10 into and out of the toolbox main body 2.
Whereas, the known electric tool in this kind has been stored in a horizontally lying position that is, for instance, the same with the position that the electric tool is laid on a flat working table. Because the electric tool has been fitted into a seat portion in the lying position, it has been troublesome to bring the electric tool out by gripping the handle.
According to the embodiment of the present invention, the electric tools 10 can be stored in a forward leaning position while their handle portions 12 are positioned to be opposed to the user. Therefore, the user can store the electric tools 10 in substantially the same position as the working position. When the electric tool(s) 10 is needed, the user can quickly and easily grip the handle portion 12, withdraw it at an oblique upward direction, and start the working operation in the same position without need of re-gripping the electric tool 10.
In this way, because the user can store the electric hand tool 10 by gripping the same maintaining the usual working position, the user can also utilize the toolbox 1 as a tool keeper for temporarily storing the electric tool(s) 10 during a machining operation, such as a boring operation.
As the electric tool(s) 10 is stored in the forward leaning position, the user who may be positioned on the front side of the toolbox 1 can store the electric tool(s) 10 by moving it in an obliquely downward direction and can bring out the electric tool(s) by moving it in an opposite direction. Therefore, the user can store or bring out the electric tool(s) 10 while he or she takes a comfortable posture without need of further bending and stretching his or her arms.
In the embodiment, the two electric tools 10 are stored in parallel on right and left sides of the battery charger 20 for the battery pack 14 of the electric tools 10 and are spaced from each other by a suitable distance. Due to this, the electric tools 10 and the battery charger 20 do not interfere with each other when they are brought in or out from the toolbox 1. In addition, the user gripping one of the electric tools 10 can quickly and easily bring in and out one of the electric tools 10 because the hand of the user may not contact the other electric tool 10.
The electric tools 10 are not stored in a simply upright position on the upper surface of the seat portion 30 but in the forward leaning position inclining the front end portion of the tool main body 11 downward. Therefore, the electric tools 10 can be stored to have a height smaller than the height in the upright position.
Various changes can be made to the above explained embodiment. For instance, electric drivers are exemplified as tools to be stored in the toolbox described in the above embodiment. Electric screwdrivers and other electric tools can also be stored in the toolbox. Furthermore, the toolbox can store electric tools that receive the supply of power from an AC power source, other than the electric tools having battery packs. Moreover, the toolbox can also be used for storing pneumatic tools other than electric tools.
Although the seat portion 30 in the embodiment has an adequate cushion property, the seat portion may be made of metal, hard resin or wood.
